The base was 12mm plywood. On top of this I bonded a commercially available, vac formed moonscape. This looked 'vac formed', not moon like. So, I drowned it in an aerosol coat of matt varnish, then sprinkled very fine sand all over the base.
Following my 'do as I say, not as I do' philosophy, before the varnish had dried, I sprayed an automotive grey primer over the surface, followed by a Tamiya white primer, almost horizontally, over the car primer grey. This picked out all the highlights on the craters.
The edge of the plywood had oak strips bonded, sanded and stained. Then I drilled the lightning bolt supports. These are 2mm piano wire, suitably contorted to look like lightning. This was then surrounded with lengths of fine craft wire, about 0.5mm in diameter, also bent into random shapes. The lightning bolts were then sprayed white, and then pink.
Two support holes were drilled in the bottom of the model ( It's okay, I threw the box away years ago..and I know what a boxed one is worth. Still, I don't care, it looks better this way! ), and the Eagle was placed on its 'bolts'.
